This invention relates to improvements in a mount for web rolls adaptedparticularly for elevating and supporting heavy web rolls in selectedpositions to be unwound and fed to a processing machine.

An object of the instant invention is to afford an apparatus in which isinitially received from the floor level of its situs, a heavy web rollto be subsequently elevated and adjusted into a selected position asrequired for unwinding of the roll while thus supported, all of whichisaccomplished with but little expenditure of physical effort upon thepart of an operator.

Another object of the invention is to providepower-driven apparatus forhanding a heavy web roll and supporting it in position for unwinding.

A further object of the invention is to construct a power drivenapparatus for handling heavy web rolls of various lengths and supportingthe roll in an accurately adjusted position relative to the processingmachine that receives the web from the roll.

And a still further object of the invention is the provision of apower-driven machine in which a heavy web roll is secured accurately onsupports therefor and'hoisted to a predetermined eleva-'.v tion, andmanually operated means by which to bodily move the hoisting andsupporting apparatus together with the web roll into selected positions.

Other objects and advantages of the invention appear in the followingdescription.

The illustrative embodiment of the invention consists of two standsindicated generally by A and B arranged in opposing positions on a sta-.tionary base I upon which both stands are movable, there being providedrollers 2 secured to the stands. by brackets 3 arranged so the rollerstravel between the flanges of the channel rails I of the base.

Each stand consists of a frame having parallel uprights 5-6 connectedtogether at their lower ends at each side thereof by side bars I thatoverride the corresponding base channel rails 4 out of contacttherewith. An oscillator (Fig. 7) is mounted in each of said framesconsisting of a head-block 8 and a tail-block 9 spaced apart from eachother and connected together by divergent arms l0, each having a hubH-l2 that has bearing in the coresponding uprights 5-6 so that theoscillators are axially alined. Each of said head-blocks has a radialextension l3, on the outer end of which is secured a U- shaped frame I4,in the arms of which is mounted for rotation an arbor I5. The arbors arenormally axially alined and have on their inner ends correspondingroll-chucks it. One of the arbors has thereon a hub [5' that is engagedby a brake-shoe I! connected with its frame, as at l8, and which istightened about the hub l5 by a hand-screw i9 to retard rotation of thearbor.

The stands A and B are connected together by a coupling shaft 20 thathas turning movement in a pendant lug 2| on the frame for the stand Aand is threaded in another lug 22 on the frame of the other stand B, sothat upon turning of the shaft the stand B is moved toward or from thestand A accordingly as the shaft is turned. The shaft 20 is actuated bya reversible motor C through the medium of a speed reducing gear 23 anda chain and sprocket connection 24.

The oscillator for each stand is individually actuated by means of acorresponding reversible motor D--E through the medium of a speed reducng gear 25, a dual chain and sprocket connection 26 including asprocketed countershaft 21, that is mounted in pendant brackets 28 onthe frame for the corresponding stand, and a slack chain 29, engagingthe countershaft, that artially encompasses the head 8 of theoscillator, the extremities of said chain being secured to the perimeterof the head by bolts 30. Provision is made for taking up the slack ofthe chain 29,

preferably consisting of a spring-pressed sliding bar 3| on the standstructure provided with a roller 32 that bears against the chain, therebeing provided a screw 33 for adjustment of the take-up device.

Endwise travel of the stands A-B onthe base is affected by mechanismconsisting of a transverse shaft 34 that is suspended in brackets 351'01 turning movement which has pinions 36 on its ends that engagecorresponding racks 31 secured on the channel rails I so that, uponrotation of the shaft 34, the stands are motivated on thebaselengthwise. Theshafttlisactuatedbya worm ll, secured on the lowerend of an operating post 3!, that engages a worm-wheel II on the pinionshaft 34. The post is rotatably mounted in brackets II and 42 that aremounted respectively on the pinion-shaft 3i and the frame for the standA, the upper end of the post having thereon a manually-operated lever 13for turning same. As the stand A is motivated, the otherstandIBtravelslikewisethroughthem-ediumoi the coupling shaft 2|.

Each stand A--B has connected therewith a transverse guide-way N, bymeans of bars II, the

ends of which project outwardly beyond the base I. Preferably, theguide-way is formed of two channel bars 84' spaced apart from each otherto afford a slot It. The guide-way II has movably mounted therein aslotted cam-plate 41 that projects up through the slot 48, and has asupportingbraceaandonsaidchannelbarsare mounted stationary cam-plates llhaving braces b, the cam-plates It being disposed astride oi the movablecam-plate. The slots l'l'll' in said cam-plates are divergent and haveextending therethrough a follower-pin I! the ends of whichareconnectedby means oflinksflwithawrist pin ii that proiects from thehead of the corresponding oscillator. Thus, when the oscillator isrotated to loading position the cam-plate 41 is caused to travel to theposition indicated in dottedlines (Fig. 3).

Each guide-way 44 has a supplemental guidefrarne 52 consistingpreferably of a pair of angle bars N that overlie the base, brackets I4being provided for securing the guide-way and guideframe together.

In each guide-frame i2 is disposed a travelingtrayltinwhicharesupportedaseriesoiidling rollers 56 that extendhamversely with respect tothebase l,thetraybeingprovidedwithrollers llthatride uponthebarsil. Eachtrayisconnected with the correspondingmovable camplate I! by means of a bracket 58. Thus, the roller tray ismoved in its guide frame according to the travel of the cam-plate 41(Fig. 3).

Preferably, the guide-frame I! is provided with rollers ilbywhichitissupportedonthebase channelrails,thustopermitfreetravelofthestandBonthebasewhentherollertl-aysare loaded with the web roll.

In Figs. 9 and 10 is shown the roll chuck II which consists of the arborll mounted for rotation in the frame ll. The outer projecting endportion of the arbor is encompased by ,a concentric axially movablecollar It provided with a series of pockets it". In the outer endportion of the arbor are a series of radialb disposed chamfers 6| thatslant convergently toward the outer end of the arbor. In each chamfer isdisposed a movable jaw ii, the rear end of which has an L-shapedextension I! that is disposed in the corresponding pocket ll", andtheforward endolthejawhasanextensionflthatprotrudes into a hollow taperedtip '4 secured on the end of the arbor. Compression springs I, disposedin the pockets it", bear upon the L-shaped extensions of the jaws tourge outward movement of the jaws toward closed position, and an annularseries of other springs it are disposed around the arbor between saidcollar and a buttvplate"onsuidai'borthattendtomovethe rangement, whenthe collar is moved backward upon the arbor, the jaws expand outwardlyinto engaging position, guided by the extensions 02 and it in saidpockets and tip.

. The motors D and E are reversible and synchronized so as to rotatesimultaneously clockwise or counter-clockwise, and thus the oscillatorsare both moved selectivelyi into loading or supporting position (Fig. 4)accordingly as .the motors are energized.

Each of the oscillator activating motors 13-12 have in connectiontherewith a magneticallyoperated brake it (Figs. 1-8) provided with asolenoid is, a brake lever II and shoe II that has frictional engagementwith a drum 12 on the motor-shaft it. The purpose of the brake is toprevent the motor from coasting while deenergized.

The motor 0 for actuating the coupling shaft 2|, and the motors D-E foractuating the osciliators, are energized by current derived from asuitable source of power (not shown) through main conductors 14 andsuitable intermediate electrical appliances and connections, commonlyknown, and exemplified in the diagram (Fig. 11). In the arrangementshown, the group of connections indicated generally by F, switches I5and It, normally open, are so connected that the closing of one or theother of the switches causes the motor 0 to rotate forward or reverse,resulting in rotation of the coupling shaft 2| and conthe stand Aaccordingly.

sequent movement of the stand B toward or from The group ofconnections,generallyindicatedbyG,areforthemain control of the motors Dand E that activate the oscillators, there being provided forward andreverse, normally open, switches 11 and II soconnectedthattheclosingofon'eortheotherof said switches causessimultaneous rotation of said motor in one direction or the otheraccordingw, and consequent movement of the oscillators into loading orroll-supporting position.

Another group of connections, generally indicated by H, is for the ingcontrol of the motor 3 that actuates the oscillator on the stand 13 bywhich the motor is activated, individually, and independently withrespect to the motor D, thus to enable the operator to maneuver the rollchuck It on the stand B into alinement with the chuck ontheotherstandAasoccasionrequires. This is accomplished by selectivelyclosing the forward or reverse switches 19-", thus to cause turningmovement of the oscillator on the stand B relative to the oscillator onthe other stand A. selectively in one direction or the other accordinglyas said switches are manipulated.

Ope ation In utilizing the invention, the machine is preferablyinstalled so the tops of the rollers II in the traveling trays arelocated approximately at the iioorlevelofthesitussothatawebmllJmayreadily be rolled directly from the floor onto the rollers of both trayswhen the trays and the oscillators are in loading position (Fig. 3) andthe stands are separated from each other sufiieiently to allow the rollto clear the chucks ll.

After the roll has been deposited on the rollers and its bore alinedwith the chucks the stand B is drawn toward the stand A by operating themotor 0, whereupon the chucks enter the bore of the roll at the endsthereof, and the roll is clamped endwise between the collars it on thecollar toward Jaw-closing position. By this arll chucks, whereupon. theiawsof the chuck expand and firmly engage the surrounding interior wallof the roll. The roll is then elevated to supporting position by closingthe appropriate switch II or 18, as the case may be, thus causing theoscillators to simultaneously turn upon their axes. After thus elevatingthe roll into unwinding position, it is jockeyed into parallelism withthe processing machines (not shown) that receives the web, bymanipulation of the switches I9 and 80. While the stands are thussecured relatively in position by the coupling shaft 20, the position ofthe web roll relative to the processing machine is further adjusted bybodily moving the stands lengthwise on the base I in one direction orthe other by manipulation of the lever 43.

The web is then unwound in the usual manner from the roll as it is drawninto the processing machine until exhausted. During the unwindingoperation the brake I1 is tightened or loosened as may be required toprevent racing of the roll or vary the tension of the web between theroller and the processing machine.

The oscillators are then returned to loading position, by closing theappropriate switch l'|18, in readiness for renewal of the loadingoperation. A particular advantage of the invention is that the sequenceof operations required for each complete performance is accomplishedexpeditiously by one operator.

Variations from the particular construction above disclosed mayberesorted to by the exercise of skill in the art, without departurefrom the spirit or scope of the invention.
